Well now that I have the time, I tried to look at that Albi L09 procedure again. Unfortunately, I had trouble downloading it and suspect that the local gateway server is the culprit. But, I've had another look at the Calais ILS24 procedure.

I have no understanding of French at all but I suspect that the speed limits relate to racetrack timing. If this is correct, then for aircraft IAS between 130 and 160 knots, outbound time is 1 min and 30 secs. And, for aircraft below 130 KIAS, outbound timing is 2 mins. I further suspect that sector entries to the racetrack are limited to a maximum timing of 1 min 30 secs, but I might be wrong about that.

I don't see anything that looks like a speed restriction on the standard 1 min holding pattern. If this is the case, you can use a higher speed than 160 KIAS to enter the hold and slow down for the racetrack.

I see that the minima box only caters for categories A to C and, while cat. C aeroplanes can handle 160 KIAS, it's a bit slow for some of the bigger cat. C types.

All in all, not the sort of procedure to start reading about just before you start to do it! This one needs quite a bit of advance planning, to get the aircraft configured early.
